Re: Big Block vs LS
The sound part well I have high flow cats on the Corvette and from what I hear it does dumb down the noise a little. The Corsa muffler gives it a little more of an exotic sound versus the Chevelle. Both engines put peak power out a like 6,000-6,200 rpm so its not like one puts out the top power at 7,500 rpm and has the super high rpm whine. The LS is a 454 so it is not a small LS and that is similar in size to what you are looking at if you went LS. Now see if you are thinking a 500-540 CID BBC that will sound great in the car and give a lot of power and that deep tone we all know and love.
